The Antique Automobile Club of America, founded in 1935, is the world's largest automotive historical society with over 60,000 members and 400 regional clubs worldwide. The AACA is dedicated to perpetuating the memories of early automobiles by encouraging their history, collection and use. The aim of the AACA is the perpetuation of the pioneer days of automobiling by furthering the interest in and preserving of antique automobiles, and the promotion of sportsmanship and of good fellowship among all AACA members. The AACA uses the term "automobile" in a comprehensive sense to include all self-propelled vehicles intended for passenger use (cars, race vehicles, trucks, fire vehicles, motorcycles, powered bicycles, etc.). Similarly, the term includes various power sources, such as gasoline, diesel, steam and electric. The AACA holds countrywide competitive and noncompetitive meets and events. These are on a divisional basis offering a program within the reach of everyone. Tours and activities relating to the hobby are sponsored, including the Revival Glidden Tour®. The annual meeting of the AACA is held in Philadelphia, Pennsylvania during February. Annual meetings feature conferences and workshops designed to educate enthusiasts on many aspects of the hobby - from restoration tips to automotive history. The AACA is proud of its relationship with the many historical organizations devoted to similar objectives the world over. The Club, through its National Headquarters, publications, library, museum, and membership, aids individuals, museums, libraries, historians and collectors dedicated to the preservation of automotive history.
